Market Characteristics

For more than 50 years, IMI Critical Engineering has been the leading provider of highly engineered fluid control solutions in the power generation, oil & gas, petrochemical, iron & steel and nuclear industries.

Each of these sectors faces a number of significant challenges including:

  • Urbanisation, the demand for resources is driving existing plants to be either more efficient or to upgrade for higher performance
  • Legislation, safety and quality regulations are getting stricter and more recently, compliance to fugitive emission standards demand better valve solutions
  • Emerging markets, higher demand for energy is driving the need for improved reliability in small capacity as well as super-critical plants, which have higher outputs and more stringent requirements, resulting in greater reliance on bespoke engineered valves

Our business is strategically placed to support all of our customers’ challenges, with proven technology, applications know-how and solutions that are sustainable and cost effective.

Engineering Advantage

We deliver Engineering Advantage to our customers through the unique combination of engineering know-how and fluid controls technology. At the heart of Engineering Advantage is customer value. Our staff of over 400 engineers worldwide understand how to convert industry knowledge, market insights, and our customer’s toughest challenges into solutions that give our customers a competitive advantage.

Knowledge & Experience

Our relentless drive to solve customer fluid control problems has resulted in the creation of two proprietary training programs:

  • The Valve Doctor® program, which is focused on developing world-class talent in the field of IMI Critical Engineering flow control solutions, and
  • The IMI Critical Engineering University, which is focused on furthering customer education on IMI Critical Engineering solutions.

We have over 50 Valve Doctors® globally and we aim to identify an additional 50 people in the next year to ensure we lead the way with our application experience. They are the result of a comprehensive, multi-year programme that exposes these experts to real world issues where they work with our customers to anticipate their future needs. Our Valve Doctors® differentiate us because they have:

  • Decades of experience in the valve market
  • Commissioned IMI Critical Engineering equipment at plants and as a result have detailed insights
  • Integral valve/plant knowledge to troubleshoot and solve customer problems

Our IMI Critical Engineering University further helps to establish us at the forefront of valve technology and is for customers who want to understand more about how to achieve the highest levels of performance and reliability.
